Disciplinary Literacy: Science

Disciplinary literacy is important because each discipline represents different cultures that: • have different purposes and approaches to knowledge

• use different methods to gain information • depend on different kinds of evidence • write different kinds of text • read with those differences in mind

To create replicable, reliable findings about scientific phenomena that can be used to predict what will happen under similar conditions. Controlled experiments and systematic observations to discover features, processes, interactions, etc. of phenomena under study. Is the evidence experimental, replicable? Is process predictable? Explanations, arguments about features, processes, interactions Experiments/findings read critically for adherence to scientific methods; replicated, reliable information read in learning mode (as with science textbooks). • Nominalization; • Long noun phrases; • Movement of verbs further into the sentence; • Hierarchical order to knowledge (need to know certain processes before understanding other more complicated ones) • Passive voice Tightly knit, highly structured, abstract, objective, multimodal Example: • Glass cracks more quickly the harder you press on it. • Cracks in glass grow faster the more pressure is put on. • Glass crack growth is faster if greater stress is applied. • The rate of glass crack growth depends on the magnitude of the applied stress. • Glass crack growth rate is associated with applied stress magnitude.
